Description
The SC4216 is a high performance positive voltage
regulator designed for use in applications requiring very
low Input voltage and very low dropout voltage at up to
3 amperes. It operates with a Vin as low as 1.45V, with
output voltage programmable as low as 0.5V. The SC4216
features ultra low dropout, ideal for applications where Vout
is very close to Vin. Additionally, the SC4216 has an en-
able pin to further reduce power dissipation while shut
down. The SC4216 provides excellent regulation over varia-
www.DatatSiohenest4iUn.cloinme, load and temperature.
The SC4216 is available in an SOIC-8EDP (Exposed Die
Pad) package. The output voltage can be set via an
external divider or to fixed settings of 0.5V and 1.2V
depending on how the FB pin is configured.
